It's not just for the car. You might start with Stereophile's recommended components. Then you might try the various mail order highend dealers, to see if you can audition any contendors. I use an ADCOM GTP-350 as the tuner, and it sounds pretty good. My Sennheiser HD-600's with my 10 year old AM/FM Walkman are unmistakably highend and high-rez. The classical station waylays me for long periods of time with these, and the inside of my skull becomes 300 feet in diameter...

OK Magnum Dynalab, Fanfare, Day Sequerra, etc. owners...I have no "high end" dealer in my area that carries a great tuner. I probably will not have the chance to listen to or 'a/b' compare a tuner before I decide to purchase. I'm asking anyone with comparison experience or anyone that feels that the own the best to respond in this discussion. Thanks, I look forward to reading your responses!
